tdom parser problems with xmlns keyword

Hi all,

I have got to parse a xml file which is always in a defined schema.So
this always comes with keyword "xmlns" at starting

I have something like
<SCL xmlns="aaa" xmlns:xsi="bbb" xsi:schemaLocation="ccc"

when I do
set nodeList [$root selectNodes //SCL ]

I get empty in variable "nodelist"
Incase I change "<SCL xmlns="aaa" xmlns:xsi="bbb"
xsi:schemaLocation="ccc"" to
then I get the root node address in variable nodeList.

Is there a solution for this keyword problem "xmlns"
